abc * xyz; Depending on what abc is (variable or type name) it can be either a multiplication or pointer variable declaration. With the new syntax ambiguity is reduced. This might not be a huge issue for people reading code (because in context it should be pretty obvious), but for compiler it means that type information is required to parse code and compiler stages get mixed together.
